Specification of Letters Patent.

`Patented J an. 9, 1917.

` Application filed October 17, 1914. Serial No. 867,159.

To all whom t mag/'concern e Beit known that I, 'JAMES DvoRAcEK, J r., a citizen of the United States, residing at Maynard, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Spikes; and YI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

The object of this invention is the provision of a spike especially designed for securing railway rails to ties and including a threaded body or shank having one' end pointed and a laterally projecting head at the opposite end adapted to coperate with a laterally projecting wing or lug to engage the base of a rail.

With this and other objects in view, the invention consists in the novel construction, arrangement andv formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing,in which: n

Figure 1 represents a side elevation of the spike applied to use. Fig. 2 represents a top plan view of the spike applied to use, illustrating the use of a wrench for turning the spike to the desired position, and Fig. 3 represents a fragmental front elevation of the spike removed. v

Referring to the drawing in detail, the numeral 5 indicates the body or shank of the Y spike having one end 6 pointed and a laterally projecting substantially rectangular head 7 at the opposite end. The top face of the head 7 is oppositely inclined so as to permit the same to be struck from various angles with a hammer or other tool without danger of the head of the tool slipping from the head of the spike. A spiral groove 8 is formed between the tapered end of the spike body and the head 7 and is designed to have the same effect as screwthreads Y when the spike is rotated. A laterally projecting wing Copies of this patent may be obtained for ve cents each, by addressing the or lug substantially rectangular in shaper9 is formed integral with the body 5 and arranged in spaced'relation Vto and under the head 7 and is connected therewith by the v'straight rail base-engaging surface 9a. The

baselO of a railway rail is adapted to be received between the head 7 and lug 9, and the top face of said lug is preferably horizontal, while the lower face of the head 7 is inclined so as to snugly fit the top and bottom faces ofl the rail base. Y Y

In use, the shank is positioned, as illustrated in Fig. l in Vthe uppermost dotted line position, and is driven downwardly in the tie 11 until the lower face of the wing or lug 9 engages the top face of the tie. is subsequently rotated one-half revolution by the tool l2 or other suitable wrench until `1t occupies the position illustrated in full What I claim is:

A railway spike including a cylindrical shank having one end pointed and a spiral groove extending from end to end thereof, a head carried by the opposite end of said shank, a lug formed integral with said body and arranged in spaced relation and inwardly of said head, and a straight surface connecting said head with said lug adapted t0 engage the edge of the base of a rail to prevent rotary movement of the spike shank. In testimony whereof I aiX my signature in presence of two witnesses.
